Adds support for Ubuntu 24.04, drops support for Ubuntu 20.04
Known issues:
- On Ubuntu 22.04, sometimes GNOME shows the wrong tray icon
- On Ubuntu 24.04, the first time you open the tray menu, GNOME takes a
long time to open the menu.

This PR creates a GTK+ event loop, a blank window, and the tray menu. It
connects to the IPC service, you can sign in and everything, but the
About window, Settings window, and Welcome window aren't implemented.
We build a deb package in CI but it isn't pushed to the draft releases
in CD yet.

Pros over Iced:
- More mature
- Easy integration with `tray-icon`
- Small binaries (< 1 MB for this example)
Cons:
- GTK 3.x is abandoned as of March. GTK 4 isn't packaged for Ubuntu
20.04.
- Widgets might be hard to use
- Hard to set up on Windows, only using this for Linux for now

- Waits a random amount of time up to 24 hours before the first network
check, to avoid the thundering herd problem
- Polls every 24 hours (86,400 seconds) after that
- Saves the network response to disk so we ~~can show "Update ready"
immediately at startup~~ won't notify twice about the same version
- Not clear whether suspending the computer suspends the timer - "it is
also not specified whether system suspends count as elapsed time or not.
The behavior varies across platforms and Rust versions."

Currently, `tunnel_test` uses a rather naive approach when dispatching
`Transmit`s. In particular, it checks client, gateway and relay
separately whether they "want" a certain packet. In a real network,
these packets are routed based on their IP.
To mimic something similar, we introduce a `Host` abstraction that wraps
each component: client, gateway and relay. Additionally, we introduce a
`RoutingTable` where we can add and remove hosts. With these things in
place, routing a `Transmit` is as easy as looking up the destination IP
in the routing table and dispatching to the corresponding host.
Our hosts are type-safe: client, gateway and relay have different types.
Thus, we abstract over them using a `HostId` in order to know, which
host a certain message is for. Following these patches, we can easily
introduce multiple gateways and relays to this test by simply making
more entries in this routing table. This will increase the test coverage
of connlib.
Lastly, this patch massively increases the performance of `tunnel_test`.
It turns out that previously, we spent a lot of CPU cycles accessing
"random" IPs from very large iterators. With this patch, we take a
limited range of 100 IPs that we sample from, thus drastically
increasing performance of this test. The configured 1000 testcases
execute in 3s on my machine now (with opt-level 1 which is what we use
in CI).
